The Pot culture studies were undertaken to investigate the resistance inducing chemicals for the management of Sheath blight of rice. Effect of certain resistance inducing chemicals viz., Acetyl Salicylic acid, Benzoic acid, Nicotinic acid, Propionic acid, Naphthalene Acetic Acid, Salicylic acid were sprayed at 20, 50 and 100 ppm conc. individually at disease initiation and repeated once at fifteen days interval under pot culture conditions. Among the various resistance inducing chemicals, salicylic acid @ 100 ppm was the most effective in reducing the sheath blight incidence followed by Salicylic Acid (@50 ppm) which was statistically at par. It was followed by Acetyl salicylic acid (100 ppm), Salicylic acid (20 ppm), Acetyl salicylic acid (50 ppm), Nicotinic acid (100 ppm), Benzoic acid (100 ppm) and Propionic acid (100 ppm). NAA at 20 ppm was least effective.
